Question Ram can't go past 2667(default)

[Ocean111]

Hi everyone, I have an issue with memory speeds.

I have an Z790 Gigabyte Aorus elite ax DDR4 motherboard, 13900KS, 4x32gb 3600 cas 18 memory, XPG core ii gold 1000watt PSU, and updated to the latest BIOS and microcode.

the memory can only run at the default speed of 2667 MHZ, when set to XMP or manual 3600- the mouse freezes completely after a couple minutes and the computer is unresponsive in BIOS or Windows 11.

Even when set to 3200mhz this happens.

It only is stable at the default speeds.

The memory was pulled from an older machine and cheaper motherboard (MSI B550 A-Pro Ryzen 5600) and used daily at XMP for every kind of developing/3D/video editing/gaming and was rock stable.

I've briefly read about how the voltage might be too low as the issue, but I am completely ignorant on the matter and wanted to see if someone has knowledge they could guide me with.

Please and thank you to the community.

Do you know if these two sticks came from a set or and just two random sticks. I would first try only one stick at a time and see if one will run at the XMP 3600MHz speed. If a single stick works then swap it out for the other one and try again. Voltage wise i would start with 1.35v, although XMP should set the voltage to this. Start at 1.35v and move it up at the lowest increment possible testing at each step not exceeding 1.45v

Thank you so much for your reply. I'm encoding a video with the ram at 2666 that is literally going to take 19 hours to export with a 13900KS to NVME 4.0 2TB that I have to do for a job that couldn't wait, but when it's finished I will go into the BIOS and try to set it at 1.35v if the XMP isn't that, and then go up one step from there...

So it really is just an issue of insufficient power?

To answer the question, yes- they are the same kit: https://www.amazon.com/Patriot-Viper-Steel-DDR4-3600MHz/dp/B08688GFPD?th=1

They were working fine at the 3600mhz in the previous, lower grade board.

🙌Thank you for your information.
